Each cell is the night that starts on that date. Hours are civil-dark time with the moon below the horizon; the green rule scales with them. Green outline: new moon. Bone outline: full moon.

Activity in past Novembers

Trondheim needs Kp 2 for the average oval edge to sit overhead. 670 of the 900 November days from 1996 to 2025 (74%) reached it in the GFZ Potsdam record, 8th of 12 months; storm days with Kp 5 or more made up 10%. Trondheim sits at 63.0 degrees geomagnetic, inside SWPC's 60 to 75 degree band, where aurora can be seen on more than half of all nights. No storm is needed: by SWPC's rule the average oval edge is overhead at Kp 2.
